Ok how about we meet up in a building you can have your FAL and i will take the SMG. Comparing a SMG to a SLR on range is pointless. You would not put the SLR up against a .50 sniper.
I have never fired a sterling i have fired a Sten, SLR and a FAl
As was demonstrated when Uzi-armed Israeli paras cleared AK-armed Jordanians out of Jerusalem.
